Lintho tse susumetsang ho Sodium carboxymethylcellulose Viscosity

The viscosity ea sodium carboxymethylcellulose (CMC) tharollo e ka susumetsoa ke lintlha tse 'maloa. Mona ke a mang a lintlha tsa bohlokoa tse amang viscosity ea tharollo ea CMC:

1. Ho tsepamisa maikutlo: Viscosity ea tharollo ea CMC hangata e eketseha ka ho tsepamisa mohopolo. Maemo a phahameng a CMC a fella ka liketane tse ngata tsa polymer tharollong, e lebisang ho ts'oaroeng ho hoholo ha limolek'hule le viscosity e phahameng. Leha ho le joalo, ka tloaelo ho na le moeli oa keketseho ea viscosity maemong a holimo ka lebaka la lintlha tse kang rheology ea tharollo le tšebelisano ea polymer-solvent.
2. Degree of Substitution (DS): Tekanyo ea substitution e bolela palo e tloaelehileng ea lihlopha tsa carboxymethyl ka yuniti ea tsoekere ka ketane ea cellulose. CMC e nang le DS e phahameng e atisa ho ba le viscosity e phahameng hobane e na le lihlopha tse ngata tse qosoang, tse khothalletsang likamano tse matla tsa li-intermolecular le khanyetso e kholo ea ho phalla.
3. Boima ba Molek'hule: Boima ba limolek'hule tsa CMC bo ka ama viscosity ea eona. Boima ba limolek'hule bo phahameng ba CMC hangata bo lebisa ho litharollo tse phahameng tsa viscosity ka lebaka la ketane e ntseng e eketseha le liketane tse telele tsa polymer. Leha ho le joalo, boima bo feteletseng ba limolek'hule tsa CMC le tsona li ka fella ka ho eketseha ha viscosity ea tharollo ntle le keketseho e leka-lekaneng ea katleho e kholo.
4. Mocheso: Mocheso o na le tšusumetso e kholo ho viscosity ea tharollo ea CMC. Ka kakaretso, viscosity e fokotseha ha mocheso o ntse o eketseha ka lebaka la ho fokotseha ha litšebelisano tsa polymer-solvent le ho eketseha ha limolek'hule. Leha ho le joalo, phello ea mocheso ho viscosity e ka fapana ho latela lintlha tse kang polymer concentration, boima ba limolek'hule, le tharollo pH.
5. pH: The pH ea tharollo ea CMC e ka ama viscosity ea eona ka lebaka la liphetoho tsa ionization ea polymer le conformation. CMC hangata e na le viscous ho boleng bo phahameng ba pH hobane lihlopha tsa carboxymethyl li na le ionized, e lebisang ho repulsion e matla ea electrostatic lipakeng tsa liketane tsa polymer. Leha ho le joalo, maemo a feteletseng a pH a ka lebisa liphetohong tsa ho qhibiliha ha polymer le conformation, tse ka amang viscosity ka tsela e fapaneng ho latela sehlopha se itseng sa CMC le sebopeho.
6. Likahare tsa Letsoai: Ho ba teng ha letsoai ka har'a tharollo ho ka ama viscosity ea tharollo ea CMC ka litlamorao ho tšebelisano ea polymer-solvent le tšebelisano ea ion-polymer. Maemong a mang, ho eketsoa ha letsoai ho ka eketsa viscosity ka ho hlahloba li-electrostatic repulsions pakeng tsa liketane tsa polymer, athe maemong a mang, ho ka fokotsa viscosity ka ho sitisa litšebelisano tsa polymer-solvent le ho khothaletsa ho kopanya ha polymer.
7. Shear Rate: The viscosity ea tharollo ea CMC e ka boela ea itšetleha ka sekhahla sa ho kuta kapa tekanyo eo khatello ea kelello e sebelisoang ho eona tharollo. Litharollo tsa CMC hangata li bonts'a boits'oaro ba ho kuta, moo viscosity e fokotsehang ka sekhahla se ntseng se eketseha sa ho kuta ka lebaka la ho hokahana le tlhophiso ea liketane tsa polymer haufi le tsela ea phallo. Tekanyo ea ho kuta moriri e ka fapana ho latela lintlha tse kang polymer concentration, boima ba limolek'hule le pH ea tharollo.

the viscosity ea sodium carboxymethylcellulose solutions e susumetsoa ke motsoako oa lintlha tse kenyeletsang mahloriso, tekanyo ea ho fetola, boima ba molek'hule, mocheso, pH, letsoai le tekanyo ea ho kuta. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho ntlafatsa viscosity ea tharollo ea CMC bakeng sa lits'ebetso tse ikhethileng indastering e joalo ka lijo, meriana, litlolo le tlhokomelo ea motho.
